For your puppys weight it recommends roughly 630g but you will know your pup if you feel he looks too skinny and needs more then do so these pups grow real fast and need a bit more at times,its just a guide,i do recommend a transition with the old food,we did try millies didnt like it budcuss lost a lot of weight and his breath was awful.Il be back on later if you need any more help.Debs got a great chart on body shape for dogs keep a check on that.Shes a very nice lady she may post it for you if you cant find it on forum.This is just my opinion but bakers is not good its full of crap,but please dont take offensce if thats what you want to feed,.Id love to see some pics of your pup.
